Why study this degree at Mines?

Underground construction and tunnel engineering focuses on some of the most technically demanding infrastructure projects in the world. Subsurface facilities must perform safely and reliably under uncertain ground conditions, tight construction constraints and long service lives. As projects move deeper, larger and into more complex geological settings, the field increasingly depends on engineers who can generate new knowledge rather than rely solely on precedent.

A PhD in Underground Construction and Tunnel Engineering from Colorado School of Mines prepares you to contribute at that level. This degree is designed for you if you want to advance how underground systems are planned, designed and constructed. Mines is known for applied engineering, and that perspective defines the PhD experience. Your research will emphasize field evidence, mechanics-based reasoning and defensible analysis tied directly to real construction challenges. You will develop the depth needed to influence engineering practice and the credibility required to guide complex, high-risk decisions.

Program Overview

The Underground Construction and Tunnel Engineering PhD is an on-campus, interdisciplinary doctoral program drawing on expertise across Mines. It is designed for you if you want to pursue original research focused on subsurface infrastructure and underground construction systems.

You will deepen your expertise in geotechnical engineering, rock mechanics, construction systems and numerical analysis while tailoring coursework to directly support your dissertation research.

What you'll study and do

Your coursework is customized to your research focus and may span civil engineering, geological engineering, rock mechanics and applied modeling. Topics may include tunnel design, ground–structure interaction, construction methods, excavation stability, monitoring and risk analysis. Coursework is selected to strengthen your research rather than compete with it.

The core of the degree is independent research. You will define a problem related to underground construction or tunnel performance, design a rigorous investigation and generate results that make an original contribution to the field. Research methods may include field data interpretation, laboratory testing, numerical simulation and case study analysis. You will work closely with a faculty advisor and interdisciplinary committee and complete proposal, candidacy and dissertation defense milestones.

What it takes to complete the PhD at Mines

Completion of the PhD requires advanced coursework, successful completion of qualifying and candidacy requirements and a defended dissertation. As an on-campus program, the experience emphasizes immersion in research groups, collaboration across disciplines and engagement with industry-relevant problems. Mines’ applied environment ensures your work stays grounded in real underground construction practice and measurable performance.

You and Mines PhD: A right fit?

You may be a strong fit for this program if you:

  • Enjoy working with complex subsurface and infrastructure systems
  • Are motivated by field-informed research and engineering judgment
  • Have strong preparation in civil engineering, geological engineering or a related field

Key Program Research Groups

Research in Underground Construction and Tunnel Engineering at Mines spans design, construction and performance of subsurface systems.

Tunnel design and ground–structure interaction
